[From the back cover:]
"Chasing thieves is work for men--not boys!" growled the official, and he threw The Three Investigators' business card to the floor. Someone had to search for the fabulous, jewel-encrusted Golden Belt, but it would not be Jupe and his friends.
Then a strange twist of fate brought the boys back on the case. Soon they were surrounded by master criminals--who would stop at nothing to keep their stolen fortune!
